523b02ea23 mac80211: fix TKIP races, make API easier to use
Our current TKIP code races against itself on TX
since we can process multiple packets at the same
time on different ACs, but they all share the TX
context for TKIP. This can lead to bad IVs etc.

Also, the crypto offload helper code just obtains
the P1K/P2K from the cache, and can update it as
well, but there's no guarantee that packets are
really processed in order.

To fix these issues, first introduce a spinlock
that will protect the IV16/IV32 values in the TX
context. This first step makes sure that we don't
assign the same IV multiple times or get confused
in other ways.

Secondly, change the way the P1K cache works. I
add a field "p1k_iv32" that stores the value of
the IV32 when the P1K was last recomputed, and
if different from the last time, then a new P1K
is recomputed. This can cause the P1K computation
to flip back and forth if packets are processed
out of order. All this also happens under the new
spinlock.

Finally, because there are argument differences,
split up the ieee80211_get_tkip_key() API into
ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k()
and give them the correct arguments.

f1a46384ad wl12xx: start/stop queues according to global per-AC counters
Split tx_queue_count to count per-AC skb's queued, instead of relying on
the skb-queue len. The skb queues used were only valid in STA-mode, as
AP-mode uses per-link queues.

This fixes a major regression in AP-mode, caused by the patch
"wl12xx: implement Tx watermarks per AC". With that patch applied, we
effectively had no regulation of Tx queues in AP-mode. Therefore a
sustained high rate of Tx could cause exhaustion of the skb memory pool.

Implementing this callback function will cause mac80211 refrain from
going to powersave state when there are still untransmitted TX frames
in the queues.
This would exactly mimic the behaviour of the legacy vendor driver which
also doesn't go in powersave mode if there are still TX frames that are not
transmitted.
This should make powersaving and rt2x00 a better couple.

77a861c405 rt2x00: Serialize TX operations on a queue.
The rt2x00 driver gets frequent occurrences of the following error message
when operating under load:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the
non-full queue 2.

This is caused by simultaneous attempts from mac80211 to send a frame via
rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame,
causing the second frame to fail sending with the above mentioned error
message.

Fix this by introducing a per-queue spinlock to serialize the TX operations
on that queue.

The current TX watermark settings cause the driver to stop queues too

Fix this by increasing the high watermark to 256 packets. Increase the
low watermark to 32 to minimize periods with queues being stopped.

Emmanuel noticed that there's no explicit checking
that prevents the driver from attempting to issue
multiple synchronous commands at the same time and
wrote a patch to check. However, his patch warns
only if a collision actually happened, an unlikely
thing since the driver mutex should be held for
synchronous command submissions.

So instead of checking that a collision happened
add a check that the mutex is held which ensures
that collisions can't happen.

a5e5aa6cee mwifiex: restore handling of NULL parameters
Prior to a5ffddb70c "mwifiex: remove casts of void pointers" the
code assumed that the data_buf parameter could be a NULL pointer.
The patch preserved some NULL checks but not consistently, so there
was a potential for NULL dereferences and it changed the behavior.
This patch restores the original behavior.

f6b4e4d476 ath9k: Fix locking issue during tx completion
The received tx status of aggregated frame without BlockAck may
cause deaf state in AR5416 cards. So the driver does a reset to
recover. When this happens, we release the pcu_lock before doing
a reset as ath_rest acquires pcu_lock. This is ugly and also not
atomic. Fixing this addresses the TX DMA failure also.

ath_tx_complete_aggr can be called from different paths which
takes different variants of spin_lock. This patch also addresses
the following warning.

dcfcbd590d ath9k_hw: Fix false tx hung detection in AR9003 chips
The edma based (AR9003 family) chips update tx status
descriptors in a common ring buffer for all transmitted
frames. Whenever tx interrupt is raised, the descriptors
are processed and tx status index is moved.

The complete tx stauts ring are updated with beacons tx status
when there are no data frames to be sent for a period of time.
In this state, transmitting data frames causes the driver to
wait for the tx status on an incorrect tx status index though
the status was updated by hw properly. The driver detects this
condition as a h/w hang and does unnecessary chip resets.

This issue was orginally reported in adhoc mode while sending
frames after an idle time.

which is obviously wrong, the user should not see the *_UCODE_API_MAX
macros but the actual ucode API versions here.

The problem are the
    #define *_MODULE_FIRMWARE(api) *_FW_PRE #api ".ucode"
which do not expand api correctly (because this is a macro itself).

Fixed by using __stringify() from linux/stringify.h.

95dac04f88 wl12xx: Support routing FW logs to the host
A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).

There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
   buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
   path.

Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.

A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

f775aa06d2 iwlagn: don't use CCK rates for P2P interfaces
P2P interfaces must not use CCK rates, only OFDM
rates are allowed. To set this up, we need to set
up the broadcast station to start with 6M instead
of starting with 1M.

Since the interface type can change, also reset
the broadcast station when RXON changes.

This will affect beacons as well.

Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.

This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
The function ssb_pcicore_init_hostmode() references

This is often because ssb_pcicore_init_hostmode lacks a __devinit

55f7782e14 zd1211rw: detect stalled beacon interrupt faster
As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt
(CR_INTERRUPT) might be lost. Problem is that when device trigger CR_INTERRUPT
it disables HW interrupt. Now if USB_INT_ID_REGS with CR_INTERRUPT gets lost,
beacon interrupt stays disabled until beacon watchdog notices the stall. This
happen very often on heavy TX. Improve watchdog to trigger earlier, after three
missing beacon interrupts.

c900eff30a zd1211rw: handle lost read-reg interrupts
Device losses read-reg interrupts. By looking at usbmon it appears that
USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS. This causes read
command to timeout, usually under heavy TX.

Fix by retrying read registers again if USB_INT_ID_RETRY_FAILED is received
while waiting for USB_INT_ID_REGS.

However USB_INT_ID_REGS is not always lost but is received after
USB_INT_ID_RETRY_FAILED and is usually received by the retried read
command. USB_INT_ID_REGS of the retry is then left unhandled and might
be received by next read command. Handle this by ignoring previous
USB_INT_ID_REGS that doesn't match current read command request.

Whereas replugging device make it functional. To solve that problem
force reset device during probe.

With patch messages are gone. Unfortunately device may sometimes
still does not operate correctly after module reload (fail to receive
data after associate), but such cases are rarer than without the patch.

9935d12651 rtl8192cu: Fix missing firmware load
In commit 3ac5e26a1e entitled
"rtlwifi: rtl8192c-common: Change common firmware routines for addition
of rtl8192se and rtl8192de", the firmware loading code was moved.
Unfortunately, some necessary code was dropped for rtl8192cu.

The dmesg output shows the following:

In addition, the interface will authenticate and associate, but cannot

b7f080cfe2 net: remove mm.h inclusion from netdevice.h
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

checking the status of PAPRD_AGC2_POWER(Log(ADC_power) measured after
last gain-change in dB) field suggests whether the PAPRD is completely/properly
done. This is an additional check apart from polling for PAPRD done bit being set.
        Susinder suggests that the ideal power range value should be
0xf0 to 0xfe. With AR9382 we do have the values in this range. to have a
common check for all platforms we take agc2_power should be atleast greater
than 0xe0
